ARRANGEMENTS FOR SEALING WINDOWS, DOORS OR THE LIKE Heinrich Hoenicke, Berlin, Germany Application February 2, 1953, Serial No. 334,697

Claims. (Cl. 20-40) The invention relates to an arrangement for sealing windows, doors and the like, in which sealing fillets with ribs engage in corresponding grooves of triangular crosssection when the window, door and the like is in the closed position.

It has already been proposed to carry out such sealing arrangements in such a manner that the window frame is composed of encircling fillets arranged on edge. However, this arrangement hasthe disadvantage that the fillets of the packings merely bear by means of a surface and it is therefore not possible to produce a complete sealing. Furthermore, there is the disadvantage that when outside windows are concerned rain water can penetrate into the packing. It has also already been proposed to effect the sealing of the window sash relatively to the window frame in such manner that fillets with ribs are arranged on the window frame or on the window sash, the fillets being arranged perpendicular to the plane of the pane, that is to say, the ribs on the window frame were directed towards the inside of the window opening and the ribs on the sash frame were directed towards that surface of the window frame which faced the window opening. The danger also existed in this case that penetration of water would destroy the sealing surface or penetration of dirt would prevent a satisfactory sealing.

This disadvantage is obviated in accordance with the invention by the fact that the sealing fillets in the closed position of the window, the door or the like are disposed in or parallel to the plane of the window or door and the ribs are tapered in a direction extending perpendicular to the closed window or door.

When using the invention on double windows, more especially sliding windows, a serrated groove is used, according to the invention, between the two sashes of the double window as well as between the window frame and outer sash, and thereby a complete sealing of the air space between the windows is produced so that there is provided a stationary insulating layer of air. The window frames are preferably made of metal, so that the serrations may be in one piece with the frame, although it is obvious that the sealing fillet can also be made separately, and be secured to a frame of the same or another material.

Several embodiments of the invention are shown by way of example in the accompanying drawings, wherein:

Fig. l is a vertical section through a single-sashed window according to the invention in the closed position,

Fig. 2 is a section in the direction of the line 22 of Fig. l and shows a construction for a double-sashed window,

Fig. 3'is a vertical section through a double window which is constructed as a sliding window, and

Fig. 4 is a horizontal section through Fig. 3 in the direction of the line 4-4.

In Figs. 1 and 2 of the drawing, the window frames are indicated by a and may be made in any convenient manner of wood or metal. These frames are provided on the inside of the window with ribs 12. More especially in the case of a metal frame, these ribs may be in one frame with prismatic ribs e.

piece with the frame. They may also be fitted on wooden frames in the form of a separate frame or even as fillets. The window sash c, which in other respects can be made in a manner known per se, comprises an outwardly directed fillet d which extends around and projects beyond the frames and which is provided on the side facing the The ribs 2 are so arranged that, upon closing the window, they engage in the recesses between the ribs b of the frames. As assumed in the constructional example, the fillet d may be in one piece with the sash frame a. If the latter is made of wood, a separate metal fillet formed with ribs is preferably fitted on the fillet d, or even an encircling metal frame formed with ribs. It is obvious, however, that the entire filled d with the ribs or the entire window frame can be made in one piece from metal.

With double-sashed windows, as shown in section according to Fig. 2, the inner fillet f on one sash is arranged in the opposite direction, that is to say, in such manner that the ribs are disposed opposite to the ribs on the other sash, so that upon closing the two windows, as will be seen from the drawing, the ribs of the two window sashes interengage on the inside.

Since in this construction the sealing means are disposed inside the space in which the window is arranged and are protected against dust and moisture penetrating from outside, it is possible to obtain a satisfactory sealing action.

Each rib has the form of an acute-angled triangle, the base plane extending parallel to the plane of the sash and frame respectively and the serrations of the serrated ribs tapering in a direction extending perpendicular to the plane of the window sash and frame respectively. Each pair of adjacent ribs are in the form of a V-groove in cross section and the top of each rib has a fiat part thereby forming a frusto-conical configuration for each rib.

In the construction according to Figs. 3 and 4, g represents the brickwork in which is secured a window frame h, for example by means of screws 1'. The upper walls and the side walls of this window frame are made substantially angular in accordance with the drawing. Provided on the upper wall is a fillet it formed with serrations, it being possible for said fillet to be made in one piece with the window frame when this is made of metal. Fillets m and it formed with serrations are also provided on the side walls. The window is constructed as a sliding window, in that the section shown at the bottom in Fig. 3 can be moved upwardly and the section shown at the top can be moved downwardly. The windows are in this case guided in the serrated fillets m and n. Each of the window sections comprises two sashes F and F The outer sash F is guided in the fillets m and n in the upward and downward movement. Furthermore, the outer sash is also provided on the side facing the inner sash F with serrated fillets 0, which are engaged by correspondingly serrated fillets of the inner sash F G represents the glazing of the two sashes. It will be seen that by the engagement of the two sashes F and F by means of the serrated sash 0, an air-tight sealing of the space between the two panes G is provided, so that a stationary air space p is formed between them. The outer frame of the two window sections, which are to be indicated as a whole by the reference A and B respectively, is of different construction for the two sections. In the window section A, the lower frame section comprises, in addition to the serrations 0 which face the inner window, additional serrations r on the underside, which engage with the corresponding serrations k of the lower window frame section when the window is in the closed position as shown in Fig. 3. The upper sash frame section of the window A is formed with an outwardly projecting fillet s which en- The inner window sashes of the two window sections A and B are secured in any suitable manner, for example, by hinges, to the outer sections and can be locked by a suitable locking means in order to have access to the space between the two windows. For opening the window, either the lower section A is pushed upwardly, in which case it is guided in the lateral guideways n, or the upper section B is pushed downwardly, in which case it is guided in the lateral guideways m. Upon opening the window section A, the serrations r and u come out of engagement and upon opening the window section B, the serrations u and v come out of engagement. Upon closing the window, however, all the serrations are in engagement with one another and effect an air-tight sealing action.

The window can obviously also be made as an ordinary double window, in which case the extensions s and t are dispensed with and the sealing of the outer window with respect to the window frame is then effected in the same manner as in the illustrated example of sealing the inner window with respect to the outer window.

In the constructional example, the frame sections themselves are formed in one piece with the serrated guideways, but it is also obviously possible to use separate fillets provided with guideways, said fillets being secured to the frame. It is preferred to use metal as the material, although other materials, more especially synthetic resin or wood, can be used, and also the frame and the serrated fillets may be made of different material.

The invention is not only suitable for the manufacture of new windows and doors or the like, but can also be used for subsequently sealing already existing windows and doors. In this case, as already indicated above, there are employed separate fillets of metal, preferably aluminum, which are nailed on to the wood or let into the wooden frame. Particularly suitable for this purpose are strips, of which one consists of a narrow strip formed with ribs and the other of which includes a lateral flange in addition to this narrow strip formed with ribs, so that they can be arranged in such manner that the strip formed with ribs extends beyond the frame.
